TIMING DEVICE FOR CARRIER-PIGEONS.

Specification of Letters Patent.

Patented Sept. 26, 1916.

Application filed October 14, 1912. Serial No. 725,595.

` Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Timing Devices for Carrier Pigeons, whereof the following is a specification, reference .being had to the accompanying drawings.

The invention relates more particularly to devices for timing pigeons, wherein the timing device is stopped or started by mechanism controlled by a shutter closing an opening leading to a compartment into which the identification band is to be placed.

An object of the invention is to provide means for positively controlling the stop mechanism for the timing device from the shutter, so that said stop mechanism cannot be tampered with, or moved until the shutter is moved to close the opening into they compartment for the identification band.

In the drawings which show by way of Villustration one embodiment of the invention, Figure I, is a perspective view of a timing device embodying my invention, one of the covers being removed to show the stop mechanism for controlling the timing mechanism. Fig. II, is a longitudinal section through the casing and through the compartments for the identification band. Fig. III, is an enlarged detail showing the shutter and the manner in which said shutter positively prevents the stop mechanism from being moved when the shutter is open. Fig. IV, is a detail perspective View of one of the lever trains comprised in the stop mechanism.

The invention, as herein illustrated, is shown applied to the timing device described in Patent No. 703,381, granted July 1st, 1902, to Edward Buysse. This timing device consistsof an outer casing 1, having a removable cover 2, and a removable cover 3. This casing is divided by a horizontal partition 4, which is formed with seats in which are located the timing devices 5, and 6. The casing is also provided with vertical partitions 7, and 8, which form two separate compartments 9, and 10, respectively.

The side wall of the casing is formed with an opening 11, which leads to the compartment 9, and with an opening 12, which leads to the compartment 10. The opening 11, is closed by a shutter 13, which is pivoted at 14, to the wall of the casing and the pivot support of the shutter which is formed integral therewith extends to the outer face of the casing, and a thumb nut 15, is attached thereto, whereby the shutter 13, may be swung so as to close the opening 11, or moved so as to uncover the same.

A shutter 16, is pivoted at 17, to the wall of the casing, and the pivot of said shutter extends to the outer face of the casing, and is provided with a thumb nut 18, which may be used for turning the shutter 16, so as to cover or uncover the opening 12.

A pawl or locking dog 19, serves to lock the shutter 13, in closed position. The shutter is formed with a curved shank section 20, and with a notch 21, into which the pawl drops when the shutter is closed for locking the same, so that the shutter cannot be turned about its pivotal support until said pawl is withdrawn. A pawl 22, of similar construction to the pawl 19, serves to lock the shutter 16. Said shutter is formed with a notch 23, into which the end of the pawl drops. The pawl or locking dog 19, is pressed toward the shutter shank by a spring 24:, while the pawl or locking vdog 22, is pressed toward the shank of its shutter by a spring 25. The springs 24, and 25, as herein shown, are attached to the horizontal partition of the casing and rest on top of each respective pawl.

The timing device 6, is stopped by a swinging lever 26, which carries a flexible finger 2 adapted to engage the balance wheel on the timing device 6. This lever 26, is pivoted to a bracket arm 28. The outer end of the lever 26, extends into the forked end 29, of a lever 30. This lever 30, is pivotally supported by a post 31, which is located intermediate the ends of the lever. The end of the lever opposite the forked end extends into an opening 32, which is formed in the locking dog or pawl 19.

From the above construction, it will be apparent that the lever 26, when swung about its pivotal support must also swing the lever 30, and the lever 30, can only be swung about its pivotal support when the locking dog 19, is swung about its pivotal support. If, therefore, the locking dog 19, is held from movement, then the lever 26, will also be held from movement, and it will be impossible to release the flexible finger 27, from the balance wheel.

This locking pawl 19, rests on the shank of the shutter and can only be moved in a direction which would release the flexible linger from the balance wheel when the end ol the locking pawl is in register with a notch in the shankot the shutter. Therefore, said pawl 19, cannot be moved in, direction to release the balance wheel except when the shutter has been moved so as to entirely close the opening ll, in the side wall of the casing.

In the patent to Buysse, above referred to, the lever for moving the flexible finger for engaging the balance wheel, rests on the locking pawl, and, therefore, when the shutter is opened, it has, been possible to tamper with the timing device by means of a wire o1: flexible strips-which. are inserted over the vertical partition 7 o r by boring a hole either through the bottom or cover of the casing, and the insertionl of a suitable wire. The timing device could thns be released and operated before the. shutter was4 closed. By,- my improvedr device, however, wherein the stop mechanism for the timing device is positively connected with the controlling. dogy for the shutter, and the shutter and' controlling dog are so formed that said; conf. trolling dogcannot be moved to release the timing device until; the. shutter is fully closed, I avoid; all possible chante` of tampering with1 the timing device through; thei openingpriorI tothe closing of. the shutter.

The stop mechanism, for the timing device 57, is precisely the same as that for the. timingl device 6, Similar letters have. been.. applied thereto, and detailed description. thereof is not thought necessary. When it, is desired to release the shutter., the levenO, is manipulated by apush button, which carriesa rodv or bar 33, in the manner fully, der scribed in the patent above referred to.

IVhile I-y have described my device as applied to a timing mechanism whereinl the balanceV wheel: isl released when. the. shutter is closed, it is obvionsthat saidf device is equally applicable to the form oftiming. de-

vice wherlein the balance wheel is stopped when the shutten is closed.

Vhile I have also shown. myv improves ment as applied to agtiming device of the4 Buysse type, it willk be apparent that said invention is not limited; to this` particular construction of timing device, but may. be.

equally used; in connectionwith other tim- Copies of this patentmy be bteneeletve cents esche by aeslresinethe Gemmilm 0.1 Paints.,

controlled by a shutter which covers an opening leading to the compartment into which the identification band is placed.

It will be obvious also that various changes in theV details of construction and arrangement of parts may be made without departing' from the spirit of the invention, as set forth inthe appended claims.

Having thus described my invention, I claim:

l. In a timing device for canrier pigeons, the.. combination of a casinghaving a compartment therein, said; casing having an opening leading to said compartment, a pivoted shutter for closing said opening, a tim-ing mechanism inV Said casing, a device movable into, engagement with a moving,
